For tumours with no or few corresponding normal tissue samples, such as lymphoid neoplasm, diffuse large B-cell lymphoma (DLBC), brain lower grade glioma (LGG), CASP3 as a negative expression of colon adenocarcinoma (COAD), and rectum adenocarcinoma (READ), we used normal tissue expression from the GTEx database added to GEPIA2 to analyse the results (Figures 1B,C). This evidence concerns the gene CASP3 and reading.
